【摘要】 石膏砌块因其主要原料石膏具有独特的分子结构而具有天然的耐火特性。耐火试验表明,用石膏砌块制作的分隔墙耐火4h,墙体不倒塌、不窜火,背火面温升较小,表明石膏砌块具有优良的防火性能。更多还原

【Abstract】 Gypsum blocks have natural fire resistance property because of the special molecule structure of gypsum. Fire test shows that division wall by gypsum blocks could not collapse and catch fire under four hours’ firing, and temperature of the back surface of wall could not increase largely. So it shows that gypsum block has excellent fire proof property.更多还原
